I have a 1993 four wins 190 horizon with the 5.0 omc cobra. I keep breaking alternator belt in half. It will sequel like a banshee for a bit at first and hold together then eventually it will do it more and more then finally brake. I have had alt. checked looks like new inside so that's not it everything else turns free and the alignment looks good. Its not throwing the belt off its just braking it in half. Any ideas? I would like to swap over to a serpentine setup if anyone knows of any kits for this model of boat. Thanks B4winn
